Flow rate adjusting plate for a rotary nozzle type molten metal pouring unit



FIG. 1 is a front view of a flow rate adjusting plate showing my new design;

FIG. 2 is a left side view thereof;

FIG. 3 is a right side view thereof;

FIG. 4 is a rear view thereof;

FIG. 5 is a top view thereof; and,

FIG. 6 is a bottom view thereof.

The characteristic feature of my design is the octagonal body shape wherein two opposite sides of the octagon are of curvilinear form and merge into adjacent linear sides of the octagon to form parabolas and wherein two circular holes are provided which are essentially coaxial with the curvilinear sides, the holes being generally aligned with the axes at which the parabolas merge with the remaining straight sides which bracket the aforenoted holes, the holes being spaced from the associated parabolas by distances no less than the diameters of the holes. 

The ornamental design for flow rate adjusting plate for a rotary nozzle type molten metal pouring unit, as shown.
